Over the last week or so I've noticed that /usr/bin/X uses loads of
memory, i.e.
$ ps aux | grep X
root 1558 1.7 74.5 3459428 1535756 tty7 Ssl+ 08:46 1:10 /usr/bin/X :0 vt7 -br -nolisten tcp -auth /var/run/xauth/A:0-zFHYma
After about an hour of use, it's using around 1.5G. I get to this
point by running KDE, emacs, Konsole and Chromium. If I quit emacs,
Konsole and Chromium, X still uses loads of memory.
Within a couple of hours my system grinds to a halt and I have to
restart X (by restarting kdm)
Wild guess, one of your virtualbox devices (input or video) is doing
that?
